I've just got the game and can't even get it started without lag, choppy music and visuals. I've signed up to the bata. When I launch the game it gets stuck on the SAGA logo and the sound is choppy. Anything I can do make it run smoothly?

In the launcher you should be able to choose the GPU you want to use. I'd pick the better one of those two which will be the 6470M at a guess.

If it's defaulting to the other, good chance it will run slowly. Is that a laptop BTW, strange to see that kind of dual GPU setup if not?

The game is fully released BTW. The Beta thread is where we're making sure the update to address some issues doesn't cause anything new and serious. We're holding off pushing that live to everyone whilst we get to the bottom of some odd framerate hits on the Samba track.

Are there any applications running that are installed by the laptop manufacturer? It's rare but sometimes other applications can slow the game down. Sometimes they offer an option to switch which GPU is used in via a taskbar icon, it's worth checking.

I'm not convinced it's not attempting to use the integrated GPU. Are both listed when you look in the Device Manager via the System Settings (under Display Adapters).

We get around 25fps on a HD3000 with an equivelent processor, the Radeon should be a little faster, so this one is a mystery.

OK, so only one GPU listed under Device Manager. At least we know that the other is likely disabled then.

Have you tried the Beta branch, previously we had issues where high fps translated into low fps as we were flooding the driver. Getting that branch and trying the game full screen with the vsync enabled should yield better performance on laptops and mobile GPU's. I'd start there.

If that doesn't work, try one of the windowed modes. If you see an improvement, it could be another application is stealing focus (i.e. trying to grab the window). Windowed modes ignore these screen grabs.

If that doesn't seem to be making a difference, check your Anti-virus is set to game mode. Sometimes AV can restrict loading files, which will slow the loading down dramatically.

Outside of that, or obvious things like rendering HD movies in the background... I'm kind of stumped. It's certainly should have the power to run the game. I'd need to get a close look at the actual system to figure it out though. What make and model is it?
